Abstract
In this article the possibilities of different laser beams regeneration after an obstacle that can be the microparticle, trapped by the beam, are examined. The comparative analysis of regeneration properties of the Bessel beams, the Gauss-Laguerre modes and other beams, containing angular harmonics, is made. The forming of such beams has the maximum effectiveness with the help of phase diffractive optical elements. The experimental results of the Bessel beams regeneration, including those of none-zero order, are presented.
